Hydrocarbon Prospect of Block VI, East Gobi Basin

Abstract:

2D seismic reflection data and magnetism data, gravity data and electrical data together define the overall subsurface structure of the East Gobi basin (EGB), and reflect Jurassic-Cretaceous intracontinental rift evolution through deposition of at least five distinct stratigraphic sequences. Three major NE-SW trending fault zones divide the basin^[. In the paper, through strata sequence description and sedimentary facies analysis, as well as zone appraisal for the oil and gas in the study area, we conclude that western step-fault zone of the block VI of EGB was most favorable pay, then the reverse faulted-nose structure in the east, while in the western slope and eastern fault zone, their hydrocarbon prospect need further proved.
